Position and orientation component 21 may determine the position and/or the orientation of the housing with respect to display 12 based on the determined changes in position and/or orientation of display 12 and the determined changes in position and/or orientation of the housing. In some implementations, position and orientation component 21 may determine the distance between the housing and display 12 based on the first motion and/or orientation output signals and/or the second motion and/or orientation output signals.

In some implementations, position and orientation component 21 may be configured to determine a position and/or an orientation of the housing based on the determined position and/or the determined orientation of the landmark, and based on the first motion and/or orientation output signals and the second motion and/or orientation output signals. For example, position and orientation component 21 may be configured to determine a position and/or an orientation of the housing based on the determined position and/or the determined orientation of the landmark, and to adjust the determined position and/or the determined orientation of the landmark based on the first motion and/or orientation output signals and the second motion and/or orientation output signals. Such a determination of the position and/or the orientation of a housing may increase the accuracy of the determined position and/or the determined orientation of the housing.

In some implementations, position and orientation component 21 may be configured to determine a position and/or an orientation of the housing based on a previously determined position and/or a previously determined orientation of the landmark, and based on the first motion and/or orientation output signals and the second motion and/or orientation output signals. For example, position and orientation component 21 may have determined a position and/or an orientation of the housing, and may then determine a new position and/or a new orientation of the housing based on the first motion and/or orientation output signals and the second motion and/or orientation output signals. Such a determination of the new position and/or the new orientation of a housing may allow position and orientation component 21 to avoid any latency arising from determining a position and/or an orientation of a housing based on the visual output signals.

For example, a user may provide one or more user inputs by speaking one or more of a type, shape, size, color, and/or other information about the blade.

In some implementations, blade effects component 22 may be configured to select the blade based on the landmark. Blade effects component 22 may include or retrieve information (for example, a database, etc.) that matches a landmark to a particular blade. FIGS. 4A-4E illustrate non-limiting examples of blades selected by blade effects component 22 based on landmarks 31. In FIG. 4A, blade effects component 22 may select blade 40 a based on landmark 31 a. Blade 40 a is cylindrical in shape and appears to extend outwardly from top of housing 30 a. In FIG. 4B, blade effects component 22 may select blade 40 b based on landmark 31 b. Blade 40 b is cylindrical in shape and appears to extend outwardly from top and bottom of housing 30 b.

Blade 40 c curves towards the back of housing 30 c, with landmark 31 d indicating the back of housing 30 c and landmark 31 c indicating the front of housing 30 c. In FIG. 4D, blade effects component 22 may select blade 40 e based on landmark 31 e (shown in FIG. 3E). Blade 40 e is cylindrical in shape appears to extend outwardly from top of housing 30 e. When blade 40 e appears on top of housing 30 e, landmark 31 e may not be not visible. In FIG. 4E, blade effects component 22 may select blade 40 f based on landmark 31 f (shown in FIG. 3F). Blade 40 f is cylindrical in shape appears to extend outwardly from top of housing 30 f. When blade 40 f appears on top of housing 30 f, landmark 31 f may not be visible. In some implementations, blade effects component 22 may select blade 40 e (shown in FIG. 4D) based on landmark 31 f (shown in FIG. 3F) or landmark 31 g (shown in FIG. 3G). When blade 40 e appears on top of housing 30 f, landmark 31 f may not be visible. Blade 40 e may be longer than landmark 31 f. When blade 40 e appears on top of housing 30 g, landmark 31 g may not be visible. Blade 40 e may be larger than landmark 31 g. Other selections of blades based on landmarks are contemplated.

In some implementations, blade effects component 22 may be configured to select the blade based on remotely received information. For example, system 10 may include a wireless communication device coupled to processor 11, and the wireless communication device may allow blade effects component 22 to receive information relating to a blade from another device. Blade effects component 22 may be configured to select the blade based on the information remotely received from system 10

For example, blade effects component 22 operating inside a first processor may remotely receive information relating to a blade of a bladed weapon for a second housing. The information relating to the blade for the second housing may include information relating to one or more of a type, shape, size, color, and/or other information about the blade. The information relating to the blade for the second housing may instruct blade effects component 22 to select a particular blade to augment the appearance of the second housing. Such a selection of a blade of a bladed weapon may allow individuals to determine how their individual hilts may appear to be augmented to other individuals.

For example, blade effects component 22 may select blade 40 a based on landmark 31 a on housing 30 a (shown in FIG. 4A). In some implementations, blade effects component 22 may remotely receive information relating to the blade for housing 30 a. The remotely received information relating to the blade for housing 30 a may indicate that an individual holding housing 30 a would like housing 30 a to be augmented with blade 40 c (shown in FIG. 4C). Blade effects component 22 may select blade 40 c for housing 30 a if blade effects component 22 is configured to select the blade based on remotely received information.

In some implementations, system 10 may include a haptic generator. Blade effects component 22 may be configured to effectuate operation of the haptic generator in response to a movement of the hilt based on one or more of the visual output signals and/or the second motion and/or orientation output signals. For example, blade effects component 22 may have selected a blade of a lightsaber for a housing of a hilt. Blade effects component 22 may effectuate operation of the haptic generator to produce a light vibration of a lightsaber. Blade effects component 22 may be configured to change the intensity and/or length of the vibration based on the movement of the hilt. Other types of haptic sensations are contemplated.

In some implementations, system 10 may include a speaker. Blade effects component 22 may be configured to effectuate operation of the speaker in response to a movement of the hilt based on one or more of the visual output signals and/or the second motion and/or orientation output signals. For example, blade effects component 22 may have selected a blade of a lightsaber for a housing of a hilt. When the hilt is motionless, blade effects component 22 may effectuate operation of the speaker to produce a buzzing/humming sound of a motionless lightsaber. When the hilt is moving, blade effects component 22 may effectuate operation of the speaker to produce a “wah” sound of a moving lightsaber. Blade effects component 22 may be configured to change the intensity and/or length of the sound based on the movement of the hilt. Other types of sounds and motions are contemplated.

Overlay component 23 may be configured to determine an overlay image. The overlay image may include a blade of a bladed weapon determined by blade effects component 22. The blade may be placed within the overlay image according to the determined position and/or the determined orientation of the housing. The determined position and/or the determined orientation of the housing may change how the blade appears within the overlay image. For example, the determined position and/or the determined orientation of the housing may change one or more of the position, the size, the shape, the tilt, the rotation, and/or other appearances of the blade.

In some implementations, overlay component 23 may place the blade within the overlay image according to a previously determined position and/or a previously determined orientation of the housing, and based on the first motion and/or orientation output signals and the second motion and/or orientation output signals. Overlay component 23 may determine changes in the position and/or the orientation of the blade based on the first motion and/or orientation output signals and the second motion and/or orientation output signals. Overlay component 23 may determine new position and/or the new orientation of the blade based on the previously determined position and/or the previously determined orientation of the housing, and the determined changes in position and/or orientation of the housing. Such a determination of the new position and/or the new orientation of the blade may allow overlay component 23 to avoid any latency arising from determining a position and/or an orientation of a blade based on the visual output signals.

Display component 24 may be configured to effectuate displaying of an overlay image on display 12. The displaying may be effectuated so that the blade appears to be attached to the hilt. In some implementations, display component 24 may be configured to effectuate displaying of an overlay image within one or more of an image, a video, and/or other visual information based on the visual output signals generated by image sensor 13.

In some implementations, display component 24 may be configured to effectuate displaying of an overlay image on display 12, which allows light to be passed through display 12 in portions in which the overlay image does not contain the blade. For example, display 12 may include one or more of an optical head-mounted display and a user of display 12 may see light from the real world as well as the overlay image. In some implementations, display component 24 may be configured to change the transparency of one or more portions of display 12. For example, display component 24 may change the transparency of one or more portions of display 12 corresponding to the blade to block light from the real world passing through display 12.

In some implementations, system 10 may be configured to provide one or more of visual, audio, and/or haptic effects to simulate interactions between a blade and an object. An object may be a physical object or a virtual object. A physical object may refer to an object in the real world. A physical object may include a static object (e.g., a still door, a wall, a rock, etc.) or a dynamic object (e.g., a moving door, a moving target, etc.). A virtual object may refer to an object generated by a computing device, such as processor 11. A virtual object may include a static object (e.g., a virtual force field, a still virtual blade of another hilt, etc.) or a dynamic object (e.g., a moving virtual blade of another hilt, a virtual blaster fire, a virtual moving robot, etc.).

Visual detection component 20 may be configured to detect an object based on the visual output signals. Visual detection component 20 may determine a position and/or an orientation of the object based on visual output signals conveying visual information within the field of view of image sensor 13.

Position and orientation component 21 may be configured to determine when the blade of the bladed weapon touches the object. Position and orientation component 21 may determine when the blade touches the object based on the determined position and/or the determined orientation of the housing, and the determined position and/or the determined orientation of the object. Other implementations to determine when the blade of the bladed weapon touches the objects are contemplated.

Blade effects component 22 may be configured to select one or more visual effects based on the blade touching the object. A visual effect may refer to one or more information that may be observed visually. A visual effect may be static or dynamic, and may be visually observable at a time, over a period of time, at a location, or over a range of locations. A visual effect may include one or more of an image, a video, and/or other visual effects. Overlay component 23 may include in the overlay image the visual effect determined by blade effects component 22. The visual effect may be placed within the overlay image based on the location in which the blade touches the object.

For example, FIG. 5 shows blade 51 of housing 50 touching second blade 53 of second housing 52. When blade 51 touches second blade 53, blade effects component 22 may select flash 54 as the visual effect. In some implementations, flash 54 may be selected at the moment blade 51 touches second blade 53. In some implementations, flash 54 may be selected for as long as blade 51 touches second blade 53. In some implementations, the size and/or brightness of flash 54 may change based on how blade 51 touches second blade 53. For example, if blade 51 touches second blade 53 slowly, flash 54 may be small and of low brightness. If blade 51 touches second blade 53 quickly, flash 54 may be large and of high brightness.

As another example, FIGS. 6A-6C shows blade 51 of housing 50 touching blaster fire 60. Blaster fire 60 may be a virtual blaster fire from a blaster of a stormtrooper. In FIG. 6A, blaster fire 60 is traveling in the direction of blade 51. In FIG. 6B, blaster fire 60 touches blade 51. When blaster fire 60 touches blade 51, blade effects component 22 may select flash 61 as the visual effect. Blade effects component 22 may also select a change in direction of blaster fire 60 as the visual effect. In FIG. 6C, blaster fire 60 has changed directions and is moving away from blade 51, simulating blaster fire 60 being reflected by blade 51. In some implementations, the visual effect may include a change in blaster fire 60 when it hits another object. For example, blaster fire 60 in FIG. 6C may travel back and hit the stormtrooper. When blaster fire 60 hits the stormtrooper, the visual effect may change to show a flash at the point of impact and blaster fire 60 may disappear. As another example, when blaster fire 60 hits the stormtrooper, the visual effect may include a pop-up dialogue from the stormtrooper containing text about being hit by blaster fire 60.

As another example, FIGS. 7A-7B shows blade 51 of housing 50 touching door 70. In FIG. 7A, blade 51 is pushed into door 70 and moved in a circular shape. When blade 51 touches door 70, blade effects component 22 may select cut mark 71 as the visual effect. Cut mark 71 may become longer as blade 51 is moved in a circular shape, with cut mark 71 following the point of contact between blade 51 and door 70. In FIG. 7B, blade 51 has completed its circular motion on door 70 and cut mark 71 appears as a hole in door 70. In some implementations, the visual effect may include a view of the other side of door 70. For example, in FIG. 7B, the visual effect may include a view of a virtual flight deck with a virtual TIE fighter on the other side of door 70.

In some implementations, blade effects component 22 may be configured to select one or more haptic effects based on the blade touching the object. A haptic effect may refer to one or more information that may be observed haptically. A haptic effect may be static or dynamic, and may be haptically observable at a time, over a period of time, at a location, or over a range of locations. A haptic effect may include one or more of a vibration, a motion, a temperature, and/or other haptic effects. For example, in FIG. 5, blade effects component 22 may select an intense vibration when blade 51 touches second blade 53. As another example, in FIG. 6B, blade effects component 22 may select a short vibration when blaster fire 60 touches blade 51. As another example, in FIG. 7A, blade effects component 22 may select a temperature higher than the ambient temperature when blade 51 is pushed into door 70 and moved in a circular shape.

In some implementations, blade effects component 22 may be configured to select one or more audio effects based on the blade touching the object. An audio effect may refer to one or more information that may be observed audibly. An audio effect may be static or dynamic, and may be audibly observable at a time, over a period of time, at a location, or over a range of locations. An audio effect may include one or more of a sound, a music, a word, a sentence, and/or other audio effect. For example, in FIG. 5, blade effects component 22 may select a clashing sound when blade 51 touches second blade 53. As another example, in FIG. 6B, blade effects component 22 may select a blaster reflecting sound when blaster fire 60 touches blade 51. As another example, in FIG. 6C, blade effects component 22 may select a blaster hitting sound and/or yelling by a stormtrooper when blaster fire 60 hits the stormtrooper. As another example, in FIG. 7A, blade effects component 22 may select a cutting sound when blade 51 is pushed into door 70 and moved in a circular shape. As another example, in FIGS. 7A-7B, blade effects component 22 may select a sound of a virtual flight deck.
